Those numbers are the IP address of the server (if it was actually a valid
IP, you can't have a '0' in an IP address, that means "Broadcast"). An IP
address is the way computers are REALLY identified on the internet.

Each computer on the 'net must have an IP address (if you dial in to an ISP,
you get your IP from their server when you connect). This is where the
domain name servers come in. I think this has all been said before, but I'll
paraphrase. This is what happens when you type a URL into the 'Location' box
on your browser:

-You type in the URL
-Your browser asks your ISP's Primary DNS if it knows the IP address of the
server at the URL
- If it knows, it feeds the IP back to your browser, and you load the page.
- More often than not, the DNS won't know the IP, but it will "know someone
who does" (so to speak)
- It will ask another DNS if it knows
- And so on....

Until a valid IP is passed back for the URL you typed in. Hope that makes
everything as clear as mud.
